Naming of "fittedvalues" inconsistent

[Adrian Schlatter]

The fit() objects returned by OLS(...).fit() and RLM(...).fit() differ in naming for fitted values.

OLS uses ".fittedvalues" while RLM uses ".fitted_values" (note the underscore).

I expect the naming to be the same in both objects.

Code to reproduce the bug:

import numpy as np
import scikits.statsmodels as sm

nsample=100
x = np.linspace(0,10, nsample)
X = sm.tools.add_constant(x)
beta = np.array([1, 0.1])
y = np.dot(X, beta) + np.random.normal(size=nsample)

resOLS = sm.OLS(y, X).fit()
resRLM = sm.RLM(y, X).fit()

dir(resOLS)[39]
dir(resRLM)[28]

Thanks for reporting. This should be fixed already in the trunk and will be included in the next release.
